Five major Japanese companies, including Japan Petroleum Exploration Co. Ltd., Mitsubishi Gas Chemical Co., Inc., IHI Corporation, Mitsui & Co., Ltd., and Mitsui O.S.K. Lines, Ltd., have come together to apply for a subsidy aimed at promoting the introduction of non-fossil energy, specifically focusing on the improvement of hydrogen supply infrastructure. The consortium is working on establishing an ammonia supply base in Fukushima Prefecture, considering ammonia as a crucial raw fuel for attaining a carbon-neutral society by 2050 and as a key hydrogen carrier. The Japanese government is actively supporting these initiatives, as evidenced by the enactment of the Hydrogen Society Promotion Bill. This bill aims to facilitate the supply and utilization of low-carbon hydrogen and its derivatives to drive the transition to a decarbonized economy. The collaborative effort by the Five Companies involves a joint study to create a base for receiving, storing, and supplying ammonia in the Soma area, with plans to extend the supply to regions in north Kanto, Tohoku, and Hokkaido. The project not only focuses on developing the necessary infrastructure but also aims to contribute to regional economic growth and decarbonization. Through public-private partnerships and support from the local authorities, the initiative seeks to accelerate the adoption of hydrogen technologies and create a sustainable supply chain for ammonia and other resources.
